Derating Timing Tables
Logic timing provided in the following sections of this data sheet and the Diamond/ispLEVER design tools are worst
case numbers in the operating range. Actual delays at nominal temperature and voltage for best case process, can
be much better than the values given in the tables. The Diamond or ispLEVER design tools can provide logic timing
numbers at a particular temperature and voltage.
